Please submit your CV in English and indicate your level of English proficiency.Participation is project-based, not permanent employment.What this opportunity involvesWe're building a dataset to evaluate AI coding agents - how well a model handles real-world developer tasks.You'll create challenging tasks and evaluation criteria within realistic simulated environments:Build realistic developer environments - a virtual company with codebase, infrastructure, and context (tickets, docs, conversations) that forms a believable development historyDesign tasks from intermediate states of these environments - craft the prompt, define what "solved" means, and ensure the task is solvable by an AI agentWrite tests that verify agent solutions - accept all valid approaches and reject incorrect ones, neither too strict nor too lenientIterate on tasks and tests based on QA feedback - review agent solutions, analyze failures,



and refine until the evaluation is fair and robustWhat This Is NOTNot data labelingNot prompt engineeringNot writing code from scratch - the agent writes most of the code; you guide and evaluateWhat We Look For5+ years in software developmentCore stack: Python (FastAPI), JavaScript/TypeScript (React), Docker, Postgres, Kafka, RedisExperience writing tests (functional, integration)English proficiency - B2+Why this is hardFrontier models are already good at coding. Creating a task that genuinely challenges the best models is non-trivial. You need to deeply understand where models fail and what scenarios reveal the difference between a good and a bad solution. Tasks have many valid solutions - writing tests that accept all correct solutions and reject incorrect ones is harder than it sounds.How It WorksApply -> Pass qualification(s) -> Join a project -> Complete tasks -> Get paidCompensationUp to $40/hr equivalent , depending on level and pace. Tasks are estimated at :20 hours each; you set your own schedule.#J-18808-Ljbffr
